Subject: [PATCH] Avoid issues with certain tasks not processing during sleep
Execute processQueue tasks during sleep: needed for console tab completions, pre join event, etc.
Upstream has set precedent that the bukkit scheduler will still tick during sleep, which avoids some problems
with plugins not accounting for the new sleep feature, but can still lead to others. Because of this we have disabled
sleep by default, which avoids the problem and makes it more obvious to check if this is the cause of issues when
enabled. We also unload chunks during sleep to prevent memory leaks caused by plugin chunk loads.
